Abstract
An implantable segmented electrode structure may be configured to conduct electrical signals between elongated conductors of an implantable medical lead and respective portions of tissue of a patient. The implantable medical lead may extend from an implantable medical device that is implanted within the patient. The segmented electrode structure includes a plurality of separate electrode surfaces. The electrode surfaces are at a plurality of different axial positions and angular positions within the implantable segmented electrode structure. The segmented electrode structure additionally includes a plurality of prongs. The prongs extend axially from a proximal end of the segmented electrode structure through the segmented electrode structure. Each prong may electrically connect to one of the electrode surfaces. The prongs may terminate distally at respective electrode surfaces. Each prong may be configured to electrically connect to one of the elongated conductors.
